Hello everyone,
I am using fgev from evd package to fitting my data with general extreme value distribution. The command I used is simple: y <- fgev(x). The error is "observed information matrix is singular;" How can I solve these problem. I tried all methods in optim and it did not work. I fixed values for scale, location and shape. This works, but I have lots of different dataset to fit, so is there any automatic ways to solve the error? Thanks!
